Condition er+ her2- advanced breast cancer
Treatments azd9496
Phase phase 1
Sponsor AstraZeneca
Start date October 2014
End date January 2017
Trial size 150 participants
Trial identifier NCT02248090, D6090C00001


This is a phase 1 open label multicentre study of AZD9496 administered orally in patients with advanced ER+ HER2 negative breast cancer. The study design allows an escalation of dose with intensive safety monitoring to ensure the safety of patients. The study will determine the maximum tolerated dose. In addition, expansion cohort(s) at potential therapeutic dose(s) in patients with or without ESR1 mutations will be enrolled to further determine the safety, tolerability, pharmacokinetics and biological activity of AZD9496

Study Design

Intervention model single group assignment
Primary purpose treatment
Masking no masking
AZD9496 dose escalation and expansion(s)
If initial dosing of AZD9496 is tolerated then subsequent cohorts will test increasing doses until a maximum tolerated dose or maximum feasible dose is defined

Primary Outcomes

Safety and tolerability
time frame: Routine safety assessments, throughout the period that patients receive AZD9496 up to 28 days following discontinuation of last dose of study treatment.

Secondary Outcomes

Single and multiple dose pharmacokinetics of AZD9496
time frame: 12 weeks
4β-hydroxycholesterol concentration in blood
time frame: 12 weeks
Antitumour activity
time frame: every 8 weeks for 24 weeks and then every 12 weeks thereafter until disease progression

Eligibility Criteria

Inclusion Criteria: Provision of signed and dated, written informed consent prior to any mandatory study specific procedures, sampling and analyses. Aged at least 18 years. Any menopausal status. Pre- or peri-menopausal women must have commenced treatment with an LHRH agonist at least 4 weeks prior to starting study treatment and must be willing to continue to receive LHRH agonist therapy for the duration of the trial. Histological or cytological confirmation of adenocarcinoma of the breast. ER-positive according to local laboratory; HER-2 negative. Metastatic disease or locoregionally recurrent disease which is not amenable to treatment with curative intent. Disease progression after at least 6 months of endocrine therapy for ER+ breast cancer.

Exclusion Criteria: Any cytotoxic chemotherapy, investigational agents or other anti-cancer drugs for the treatment of advanced breast cancer from a previous treatment regimen or clinical study within 14 days of the first dose of study treatment. Any unresolved toxicities from prior therapy greater than Common Terminology Criteria for Adverse Events (CTCAE) grade 1 at the time of starting study treatment with the exception of alopecia. Presence of life-threatening metastatic visceral disease, uncontrolled central nervous system metastatic disease or symptomatic pulmonary lymphangitic spread. Any evidence of severe or uncontrolled systemic diseases, including uncontrolled hypertension, active bleeding diatheses, or active infection. Unexplained symptomatic endometrial disorders. Uncontrolled symptomatic thyroid dysfunction. Inadequate bone marrow reserve or organ function
